Greasy Pete is a grizzled old man who lives in a tunnel. He's senile and batshit insane (the two are unrelated - he was just as crazy in his youth). He spends his time scavenging for food, sitting in his dilapidated Lazy Boy, arguing with his wife (Cranky Pat), and cooking "food" with recipes he found in an ornate (albeit old and worn) recipe book. He is very defensive of this (letting not even his wife look at it's pages). Probably because most of the book's pages are blank, torn out, or worn beyond legibility. When approached by strangers, he is generally "calm", trying to sell them his meals and other junk. Dangerous when provoked (guns and other weapons).
Despite his insanity and senility, he is still very much in love with Pat.
